b20b vtec w/jun 3's not revving
for my b20b vtec, just installed jun 3's. i'm using 108 degrees cam setting but the engine's very reluctant to rev past 7500rpm.
this set-up supposedly should be able to rev happily up to 9500rpm & makes about at least 200+whp, no sweat! but mine has **** like top end
tried to advance 3 degrees intake & retard 2 degrees exhaust. but still to no avail in power making past 7500rpm.
compression is 11.6:1, bottom end fully balanced & lightened. ecu is fine, its custom obd1 program. head ported, jun racing valve-springs, 330cc injectors & upgraded fuel pump.
my car have just about everything, but isn't making power...
please advise me what to do....

have you swapped ecu's?
It might have a lower redline in the program.
Try an OEM one just to rule out any problems with the ecu you have....

yes my vote would be ecu
also: are you using intake header and exhaust? maybe the engine isnt getting enough air.
what about your fuel setup?
